Sweep my Lum

My granny and her neighbours used to talk about their need to have their chimneys or lums swept .

I then looked up Lums for a definition and promptly fell about the floor laughing .

Scots word for Chimney or flue,allows the reek to exit a house!

19-20th century vernacular for the vagina. A 'lum' was initially a slang word for the flue that drew smoke from an open fire up to the chimney on the rooftop. Lum as a slnag term is quite popular with women of a certain age and social background.
